ARTIFICIAL FIIlAMENT SPINNING FRAME.

applicati mea August 27, i925. serial No. 52,765.

To; all 'whomz't may concern.' o Be it known that THOMAS HARRIS, acitizen in the United States, residing at Woonsocket, in the 'county ofProvidence and State of Rhode Island, hasinvented certain new and usefulImprovements in Artificial Filament Spinning Frames, of which thefollowing is a specification. 0

My invention relates to improvements in machines for spinning strands ofartificial fibres, filaments or the like and comprises in combinationmeans to center and'support the up er ends of the spinning boxes thereofduring the spinning process.

After the fibre, or filament has been formed in the spinneret or othermachine in vthe usual manner, it is led through a glass tube and spuninto a cheese inside of a rotating spinning boxe A plurality of spinning-boxes are normally mounted on a frame generally similar to a cottonspinning frame and are v suitably simultaneously' driven. Hitherto as nosupports have been provided for the upperends ofthe spinning, boxes lthey have ad to be frictionally driven for if positively driven andallowed to be brought to full speed at once, bein top heav they wouldwobble severelyv an tend to yofl'. Thus it has been' necessary to emploa friction drive to ease the starting up o the machine. Due to the slipage of the ,friction drive" these machines ave been very inefficient,the spinning boxes be ing driven at varying speeds less than full speeda great portion of the time, and thus not im arting the desired amountof twist per unit length to the filament. By centering and supportingthe upper ends of the spinning boxes, I vpermit a positive drive terefor tobe used, thereby eliminating the necessity for a.. frictiondrive with4 its consequent loss of efficiency and permitting themachines tobe brought .to full speed almost at once and continuously runwithout lsli ping. As I preferably also clamp down t e l upper ends ofthe rotating spinning boxes I provide means to center and support themso they will not wobble or fly ofi' in use. The type of spinningmachines to which my invention relates is admittedly the best type ofmachine for Spinnin artificial silk but prior to my invention t is typeof machine as generally been considered inefficient and actuallydangerous tothe Workmen..

Employing my invention, the spinning v than formerly, thereby boxes maybe rotated at a greater speed l iving a greater amount of twist per unitength to the fila. ment thanliitherto thought 1possible, thus greatlyincreasing the strengt of the spun filament.

Employing m invention the size of the spinning boxes t emselves may beincreased. In actual ractice I have doubled the diameter of ihe spnningboxes thereby many' times increasing their volume. A further difficultyin employing machines of this type has been the on V'time spent in andvt e labor cost of frequent dofiing. As I greatl increase the size ofthe spinning box and ecrease the frequency of dofiing the labor cost' ofoperation is much cut down.

Hitherto due to the small size of the s in@ ning box the artificial silkor other fibre ad to be knotted between each run, `thus providing a lare number of objectionable knots in the finis ed yarn. Employing my inthecheese as the radial'distance of the guiding tube v:from the ed e of thecheese is always constant. Hit erto with wobbly spinning boxes thisradius 'has been apt to vary, thereby producing objectionablekiuks i inthe yarn.

These and such other objects as may hereinafter appearvwill be bestunderstood from a description of one embodiment thereof such as is shownin the accompanying drawin s.

n the drawings, Fig. 1 is a side' elevation of a spinning box employingmy 'invention an vincluding the driving means thereof.

.,Fig.2'is a sectional view of-the up er end ofthe Spinninv box with ininvention attached, the rais position of the'supporting arm and rotatingcollar ybeing shown in dotted lines. i

Fig. 3 is a sectional view taken along the line 3-3 of Fig. 2.

Fig. 4 is a sectional View of the hase of the spinning box illustratinginv detail th positive drive 'I preferably employ.

`vention the number of necessary knots and Fig. is a detailedsidefelevation illustrating the positive drive connection bepluralitynormally employed on this type of spinning frame, with its suitablerotating means andthe means I employ to center and support the upper endthereof. Itis obvious however, that the plurality of spinning boxes 10are mounted'on the frame and are all simultaneously driven in similarfashion from a common driving shaft 12 which extends longitudinally ofthe frame and that the means for centerin and supporting the upper endsof eac lrotating spinning box are suitably pivoted to a common shaft 14which is preferably the usual side bar of th'e spinning frame. Though itis obvious that a plurality of these spinning boxes'are normallysimultaneously driven in the frame, in the s ciiication and claims Iwill refer to one spinning box 10.0111 The spindle 16 extends verticallyupWar s from the frame of the machine, and has the spiralv gear 18 fordriving purposes Vmounted thereon, whichis driven by the spiral gear 20suitably mounted onthe driving shaft 12, which as explained is common tothe ,driving elements of all the spindles on the frame. The lower end ofthe spindle may be suitably enclosed within the housing 22. The upperend 24 ,of the rotating spindle, (Fig. 4)A is suitabl centered on theframe by means of the bearing 26. Thou h any type of bearin 26 may beemployed preferably employ t e ball race 28, which as shown comprisesthe usual collar 30 firmly secured to the upper end 24 of the rotatingspindle 16 having the circumferential ball receiving channel 32 on theperiphery thereof, the cooperating ball receiving channel 34 on theinterior of the bearing 26, and the balls 38 mounted in the usualfashion within said channels 32 and. 34 to permit revolution of thespindle 16 therein.

The usual spinning box 10 is mounted on the upper end of the rotatingspindle 16. rlhis comprises the usual base 40 and detachable cover 42.As usual the spinning box 10 is of substantially cylindrical shape andis preferably slightly upwardly tapered so that the cover 42 may bereadily removed from the base 40 thereof to permit y withdrawal of thecheese 44.

As stated previously the main feature of my'invention is, incombination, means to center, support and align the upper ends of therotating spinning boxes so that the size of the boxes 10 may be greatlyincreased as well as the speed of revolution thereof. In combinationwith said means I preferably employ a positive drive for said rotatingspinning box 10, though it is obvious that a frictional drive with-itsloss of efficiency still may be employed if desired. To form a positivedrive connection between said rotating spindle 16 and spinning box 10 Ipreferably secure the collar 45 .to the upper end 24 of the rotatingspin# dle 16 and I preferably provide the upper edge of said collar 45with the upwardly extendingsplines 46, (Fig.`5). I. provide the base 40of said spinning box within the sleeve 48 projecting downwardly 'fromthe center thereof and I provide onthe lower end of saidsleeve thegrooves 50 toreceive the splines 46 of said spindle collar 45 therein tosecure a positive drive of said spinning box.

As stated the filament 52 suitably formed as usual in thespinneret orjin thel ',plurality.- t

the gui e 54, (Fig. 2). The fi ament rough the cup 56 on the upper endof the guide tube 54, projects through the lower end 58 thereof, and isspun and radiall Wound into the cheese 44 formed from t e outsideinwards within the spin-- ning box 10. The spinning tube 54 is non-Vrotatably held by thehisu'p'port 60. The plurality of tubes 54 and.thesupports- 60 are vertically reciprocated or traversed up and down bythe usual means notv shown, to suit'- ably wind the spun filament 52 upand down within the spinning box 1010 form the cheese 44. Asstatedfthfchief feature of my invention f comprises' in combinationmeans attached to said machine to center and support' the upper endsv ofsaid rotating lllU arms, 62 suitably spaced thereon so thatr there willbe one for each spinning:1 box. Ifdesired for adjustment as shownl saidarms 62 maycomprise the two arms 62aand 6 2b longitudinally andtransversely relatively 'adjustable by means of the bolts 64 thereof. nthe outer end of said arm 62 I rotatably mount in `any suitable fashionthe rotatable collar 70. Though any means may be provided to suitablymount said rotating collar `70 on the end of said supporting arm 62 Ipreferably employ the ball race 72, which comprises the cooperatingcomplementary peripheral channels 74 and 76 on the collar 70 and outerend of the arm 62 having the rotating balls 78 therein.

It is obvious that the vertically reciprocal non-rotating guide tube 54may reciprocate upand down and be contained within the rotating collar70. To clamp-the rotating collar 7() within the rotating spinning box 10in thev lon itudinal and transverse slots 66 1115 to secure saidrotating spinning box against vertical and horizontal movement Ipreferably downwardly taper the lower end 8O of said rotating collar andI provide in the center of the to of the cover 42 of the rotatingspinning ox 10 the complementary downwardly tapered hole 82. It isobvious that the tapered lower end 8O of the collar 7() securely fittingwithin the tapered hole 82 in the top of the cover of the spinning box10 may revolve therewith and that the collar 70 suitably revolublymounted as explained on the arm 62, clamps down and supportsthefupper'end of the rotating spinning box 10. I preferably provide theouter end of the arm 62 with the detachable half 'bearing 84 which maybe readily removed if desired. The weighted reinforcing disc 86 may beattached to the to of the cover 42 of the spinning box 10, if ,esired.

After the cheese 44 has been spun to the desired size, in order to doti,it is merely necessary to reciprocate the guide tube 54 to its uppermostposition as shown in dotted lines in Fig. 2 and to raise the rotatingcollarO away from the upper end of the rotating Spinnin box l0 therebygiving room to remove t 1e cover 42 of the spinning box away from thebase 40 thereof to permit withdrawal of the cheese 44. After the cheese44 has been removed, the cover 42 is replaced, the ivoted arm 62 swungdown until the tapered lower end of the rotating collar 70 compactlyregisters in the cooperating tapered hole 82 1n the upper end of the sinning box 10 to securely clamp down sald spinning box 10 when after themachine is started up the end 52 is again fed through the reciprocatingtube 54 and a new cheese 44 is spun as usual.

It is obvious that by providin means to center and support the up er enof the rotating spinningbox that have eliminated the kinkly yarn formedby wobbly spinning boxes, that I have permitted a positive drive to beemployed, that I have made possible a greater twist .to be imparted to'the yarn, that I have permitted a much larger box to be employed, thuseliminating the large number of knots formerly necessary, and the costof fre nent dofiing.

It is understood that my invention is not limited to the specificembodiment shown and that various deviations may be made therefromwithout departing from the spirit and scope of the appended claims.
